2 The Company responsible for fresh water distribution & sanitation serving citizens ( customers) and expanding 250 employees Water Network 2.300km of water pipes 50 Tanks 52 Pump Stations m³ daily production Sewer Network 1.900km of sewer/stormwater pipes 54 Pump Stations 3 Waste Treatment Plants combined network (sewer and storm water)

3 The GIS Department ArcGIS Server 10.1 / ArcGIS Desktop 10.1 SQL Server 2008 R2 on Windows Server 2008 R2 12 ArcGIS Desktop licenses ArcGIS Online, Flex & Silverlight for ArcGIS Server Web Mapping Applications MobileWeb maps for ios & Android devices ArcGIS Mobile for Windows 7 (Tablets) 8 employees (5 + 3 internships)

4 Implementing GIS Milestones Building GIS Data for sewer network from scratch ArcInfo 7 on UNIX Building GIS Data for water network from scratch Setup Hydraulic Model for the External Water Network Serving GIS Data on the intranet through Web Application Online DB Connection between GIS and Customers DB (Sewer) Serving data to the Hydraulic Model Field crews use tablets for online mapping with the GIS Server Online connection between Call Center & GIS

5 Implementing GIS External Contractors As Built Drawings, Technical Specifications, Approval of deliverables Field Crews Water & Sewer, Daily Feedback, Inconsistencies with GIS Technical Departments New Designs, Construction Supervision, Hydraulic Information G.I.S. Technical Departments ArcGIS Desktop, Silverlight, Flex, Tablets (ios & Android), ArcGIS Online Web Applications Divisions of Water & Sewer Flex, Tablets (ios & Windows) Division of Consumers Consumption Data Data Capture with GPS Devices Hydraulic Model SW Designs for new areas, Bidirectional data flow, Hydraulic Information Customers DB Sewer Customers DB, Water Customers DB(Pilot) Upper Management Statistical Data, Maps of Strategic Content Technical Data Warehouse Electromechanical Data Borehole Data Water Flood Data Facilities Image Library As-Built Drawings Hydraulic Data Network Damages Data Upper Management Flex Tablets (ios) Process Technology Data

6 Spatially enhanced water consumption data Automated process for water consumption calculation User defines on the map specific geographic area Historic water consumption data from ERP is used A Model in Model Builder has been set up The Model has been published as a service in ArcGIS Server The service is served to the end users via ArcGIS Online Web Mapping Application or via Flex technology

7 Spatially enhanced water consumption data The Model

8 Spatial enhanced water consumption data

9 Optimizing Routes for meter collection data Old Routes Existing routes are not spatially intelligent Have been changing over years in random ways High cost in money and time due to lack of spatial intelligence Were not presented on maps

10 Optimizing Routes for meter collection data New Routes - Methodology Capturing existing old routes with mobile devices On site visits for inconsistencies between paper records & reality Proposed new geographically-wise routes for approval Compatibility edits between GIS and ERP customer data

11 Capturing basemap (cadastral) data Data Collection with mobile phones when data does not exist or is inconsistent with reality by GIS personnel and field crews - attribute data of buildings - street names & house numbers

12 Capturing basemap (cadastral) data Thessaloniki Water & Sewerage Company S.A.

13 Capturing network assets with GIS & GPR Detecting water leakages Capturing underground infrastructure

14 Inspecting new sewer pipe External contractor delivers as build drawing Camera inspection along with GIS, finalize the delivery process

15 Managing Customer Calls out of the office The process Call center inputs customer call regarding network failure Incident address in selected from a GIS Geocoding database A Map link is activated next to the incident Field crews see the map on the go while accessing incident data before even reaching the place of incident

16 Managing Customer Calls out of the office - The incident map link the incident Geocoded address

17 Managing Customer Calls out of the office - The map

18 Replacing damaged water valve Thessaloniki Water & Sewerage Company S.A.

19 The road ahead we are in the process of establishing a vertical data management system we have already captured existing company s processes restructured and improved company s processes at the moment changing our ERP and shifting to SAP next phase will be to connect GIS with SAP

20 Functional Representation Customer Claims Investment Program Systemic Representation Customer Care accounting updates in real time New Connections Construction Management Fixed Assets Register Accounting Call Center Damage Verification G.I.S. MIS Technical Actions Scheduled Maintenance Service Management Warehouses managerial reports based on financial & technical data
